Hi Scott, sorry I missed this thread before. Let me tell you about my limited experience. I started with the Amphibico housing for the HC7 with twin Salvo 50 watt lights. I personaly had problems with this housing, many people do not. I just received a Light and Motion Bluefin housing with Sunray 1000 lights. I am gong to use the Salvo's when I go up your way (diving out of Brockville) and Northeast wreck diving. I have the Sunray's for tropical diving, the fact that I can adjust power will help tremedously going from macro to wide angle. I personally use Sony Vegas and it is quite a bit more than I can handle, I am sure as time goes by I will catch up with all the functions. I am currently reading the manual and learning the housing but I will get a chance to use it next week in Cozumel, so maybe I'll have some more feed back soon.
All the best with your setup maybe if I'm in your neck of the woods I can follow you and peek at the shots your taking ha ha ha ( I did that last time in Coz following the local videographer, got some nice shots that way)
Be safe and have fun

My L&M Bluefin HD housing for FX1 rocks. Rock solid, can be balanced with or without lights in fresh or salt water.
I think if I needed to do rapid "manual" focus changes it might be a bit slow due to the electronic controls, but that's not something I find myself needing to do at this point.
I use the salvo Dual 50's HID and they are great lights, and integrate well with my salvo primary on the E/O connectors and hopefully my suit heater soon
